Delineating shallow basement faults on high-resolution seismic reflection data plagued with extreme static in NE Wisconsin, USA

Shallow high-resolution seismic reflection techniques proved valuable in detecting, delineating, and advancing interpretations of a regional fault and associate local structural features previously speculated from sparse well data in northeastern Wisconsin. This seismic survey was the first of its kind in this part or Wisconsin and provided solid evidence that the method will work well in this region. Static artifacts on shot gathers were pronounced, and if processed using more routine approaches would have inhibited confident and accurate interpretations of faults along these profiles. CMP stacked sections across these interpolated fault zones uncovered unique and unexpected attributes of the fault feature and associated structures.
